Structure of simple submersible electric propeller thruster capable of diving deep into water over 1000m and maintaining free to enable oil to be waterproof and sealed

Abstract

The invention discloses a structure of simple submersible electric propeller thruster capable of diving deep into water over 1000m and maintaining free to enable oil to be waterproof and sealed. The structure of simple submersible electric propeller thruster capable of diving deep into water over 1000m and maintaining free to enable the oil to be waterproof and sealed is characterized in that at least a rotor (2) or the rotor (2) and a stator (1) are encircled by a wide type metal seal isolation shield (5) in a stereoscopic form, the bottom of the metal seal isolation shield is provided with arotating shaft (6) which can penetrate through a motor shaft seal (7) downward, the metal seal isolation shield is filled with oil liquid (S), the external high pressure water body is carried out topenetrate through upward by a motor shaft seal (7), all the splicing gaps involved in the metal seal isolation shield are connected through a non-removable welding process, and the motor is arranged in a vertical state. The submersible electric thruster including a propeller (11) is arranged on the rear end of a main body of the submersible which is used for storehouse, and the connection betweenthe propeller (11) and the main body of the submersible which are independent is detachable.

Description

technical field [0001] The invention relates to a structure of an ideal submarine electric propeller propulsor capable of deep diving over a thousand meters and free from maintenance, allowing oil to seal against water. Background technique [0002] Present submarine, its diving depth is limited, for example: be difficult to reach the depth of nearly 1,000 meters; Reason is many-sided, and wherein waterproof sealing measure is unsatisfactory one of reason of an extra large. ——People's conventional thinking is: use rubber or plastic-based flexible polymer materials to make sealing ring components and matching sealing structures to achieve conventional waterproof sealing measures. [0003] The maximum diving depth of submarine has always been a problem that people want to solve, otherwise, it will directly affect the exploitation of seabed combustible ice in the future (commercial exploitation is also a problem that has not been properly resolved in the world). ——Its reserves...

Problems solved by technology

[0005] ——The fatal flaw of the submersible pump as the prior art is just that: the diving depth is very shallow (generally no more than about 10 meters) and the maintenance work (not maintenance) that needs to be lifted out of the water regularly to remove seepage, and the deeper the diving, The shorter the period of the above "regular"
